问题 <div style="float: left; height: 20%; width: 70%;"</div> <div style="float: right; height: 20%; width: 30%;"> </div> In Chrome the two divisions are in same line. But there is a small gap between the two divs. But in Firefox there is no gap. Why is this happening? Any solution for this? 回答1: Chrome rounds all widths to integer pixels. Unless your container width is divisible by 10, this means that the float widths will get rounded so they're not actually 30 and 70 percent of it, and as a

I use this function to send html file to client, but in client I get nothing (blank page) without error. Something I wrong?, please help? var express = require('express'); var fs = require('fs'); var app = express(); app.set('view engine', 'jade'); app.engine('jade', require('jade').__express); app.get('/test', function(req, res) { fs.readFile(__dirname + '/views/test.html', 'utf8', function(err, text){ res.send(text); }); var port = process.env.PORT || 80; var server = app.listen(port); console.log('Express app started on port ' + port); My test.html file <!DOCTYPE html> <html> <head> <meta

Vertical alignment text in container WebKit vs Firefox

阅读更多关于 Vertical alignment text in container WebKit vs Firefox

The problem is that Firefox and WebKit based browsers seem to align text vertical in different way when contained in a element that have a even height/line-height and the font-size is uneven (or vice versa). I have looked at some similar thread, but I haven't really seen any great explanation for my question. Consider http://alternativeto.net/test2.htm . This is a really simple page with just .box { font-size: 15px; font-family: Helvetica, Arial; background-color: Blue; height: 20px; width: 60px; color: White; line-height: 20px; } And <div class="box"> A text. </div> If you open that page up

I have a workflow model. Internet Explorer doesn't support some features required for model editing functionality (and regular user doesn't need it). I want a read-only preview of my model. Is it possible to server-side render my HTML to an image? I would prefer offline solution to allow our system run in corporate LAN without access to internet. jonny Here are 'local' solutions: wkhtmltoimage from the wkhtmltopdf package does exactly its name says PhantomJS more advanced capabilities, like evaluating any js code in the page's context before rendering it to an image or pdf.

Is DOM rendering GUARANTEED to block during a single (synchronous) function's execution?

阅读更多关于 Is DOM rendering GUARANTEED to block during a single (synchronous) function's execution?

问题 DOM blocking is something many people not familiar with JavaScript's strictly single-threaded synchronous execution model find out about the hard way, and it's usually just something we want to work around somehow (using timeouts, web-workers, etc). All well and good. However, I would like to know if blocking of the actual user-visible rendering is something you can actually rely on. I'm 90% sure it is de facto the case in most browsers but I am hoping this isn't just a happily consistent
